07 Extended Cap Subs Help

[FastFocus]

So, i'm looking at some options for adding some subs into my truck. I've looked into the stealth box that goes in place of the middle seat, which i think is too expensive. And i believe i've decided i want to go with 2 10" Alpine type R's. I had 2 12" Type R's in my old car and they sounded perfect with an Alpine 500watt amp. It wasn't the loudest thing in the world but it sounded good and clean.

Anyway, my concern is... i have an extended cab, and need help on where to put the subs? It looks like my only option is under the rear seat, so... Will 2 10" Type R subs fit under there? Any help or anyone with experience would be a great deal of help!

Thanks,
